The Flare Stack mod is incredibly useful for getting rid of unwanted items. However, there are a few fairly significant omissions from the list of things it can incinerate. Science Packs - which I don't much care about - and Rail. That last one is pretty big for me, because both my character and my Spidertrons end up picking up rail pieces accidentally while working near the train tracks, but those then clog Incinerators when they get scooped up by the Logistics system out of the respective trash slots.
Would it be possible to include the rail item in the list of things that can be incinerated? I understand it's not as straightforward to do it procedurally since - near as I can tell - there is no actual rail item. There's a Rail Planner that poses as the rail item. But it should be possible to include a special-case exception for that. Rails are a standard part of industry, same as Furnaces or Concrete or Electric Engines. It would make sense for them to be voidable in an Incinerator.
